Description of the invention (2) Take out. In any case, once the disc is taken out of the case, a sensing hole that can sense that the disc has been removed is permanently changed to the open state, so that the sensing hole cannot be changed to the closed state. Therefore, it can be determined whether the disc has been removed from the case. Similarly, in the third type of cassette, the 'induction hole was opened at an earlier stage, and it can be determined whether the disc has been removed from the case' so the disc can be removed from the case without restriction or Was placed. And 'Card E has a write-inhibit hole (also known as " identification switch for write protection "), and according to the standard on page ρΗ_69, (standard at page PH-6 9) When the hole is closed, page writing is possible, and when the write-inhibit hole is open, 'page writing is impossible. In other words, the g user needs to protect the data written by him to avoid unnecessary copying or erasing. The corresponding write-inhibit hole in the closed state is changed to the open state, so that the recording device cannot record the corresponding card. Tray of discs. However, in the case of using the second type or the third type cassette, a bare disc may be used without the above-mentioned case. Therefore, the disc can be used in a thin recording / reproducing device, such as a laptop computer that cannot use a cassette. However, the above specifications cannot define any write-protection mechanism, except for the write-inhibit hole of the case connected to the cassette. For example, after removing a disc installed in a write-preventing case, a user inserts a disc into a thin recording / reproducing device that cannot use a cassette, by which the writing hole is prohibited Write protection is no longer useful. Furthermore, there are many DVD-related specifications, such as the DVD-ROM specification (using the _ memory specification), and the DVD_R specification (for the recordable disc). Moreover, many have not yet been established for rewritable DVDs.

However, the group authentication flag, that is, the "group write protection" flag cannot be used. This method is quite effective when there is no write protection for only a certain group, and when the bit b4 in the group authentication flag is generally “reserved” as in the traditional specification. The present invention can be used without write prohibition In the case of holes, and the information on the disc can be effectively protected in the case of using the write-protection information on the disc. 囷 6 is a procedure to explain the writing according to a preferred practical example of the present invention. Method of protection. First, the process first checks whether a disc has been installed in a case (step S1 01) and if the disc is already installed in the case, the state of the write-inhibit hole of the 2 body is already Is checked (step S102). That is, 'when the write-inhibit hole is closed, it means that the cassette is not in the write-protected state.

Description of the invention (13)-The state of the write-inhibit hole does not match (step sl06). Even in step S1 06, the write protection status of the disc and the cartridge do not match. If the write protection flag of the disc authentication flag is set to the write protection status at step si〇5, or if Either the disc or the case indicates the write-protected state, then it is checked whether the disc is set to the " hard write-protected " state (step S1 07). If the disc is set to " hard-write In the protection status, in addition to the user data area being prohibited, data is written to the entire disc including the lead-in area and the lead-out area (step sl08). Otherwise, except the drive test area and the defect management area (DMA) are prohibited In addition, the data is written in the user data area (step S109). If it is determined in step S105 that the write-protection flag of the disc-only authentication flag is not set to the "write-protected" state, check whether the group The write protection flag of the authentication flag is set to the "write protection" state (step SU0).

Description of the invention (14) Write-protected state, or change the write-protected state of a disc to become a rewritable state. A method for updating the write-protection information is explained below, and the flowchart in FIG. 7 is referred to. In 囷 7 ', when a disc or a cassette is inserted into the recording / reproducing device, its write protection signal is checked (step S201). Then, the process decides whether the write-protected information has been used by the user (S202), and when the write-protected information has been input by the user, the process determines whether the information set by the user is used for write-protection ( Step S203). If the information set by the user is for write protection information, the corresponding write protection flag of the disc is set to the write protection state (step S204). When the information set by the user is not write-protected information in step S203 ', the flow determines whether the information set by the user is write-protected release information (step S205). If the information set by the user is write protection release information, the flow determines whether the current disc is in the hard write protection state (step S206). If the current disc is in the hard-write-protected state ', the user is informed that the write-protection cannot be released (step S207). If it is determined in step s206 that the disc is not in the hard write-protected state ', the corresponding write-protection flag of the disc is set to a rewritable state (step S208). And 'when the setting of the write protection of the disc or the release of the write protection is completed, that is, steps S204, S207, or% 08 are completed, and the disc has been installed in the case In step S20g, the result of determining the state of the writing hole of the box body is consistent with the write protection information stored in the disc.

Description of the invention (16) Read ° If the contents of the read flags are consistent with each other, it is deemed that the disc has been set as write-protected. For example, "Four flags are only written in the disc identification area of the lead-in area" and disc identification information of 1 block (one byte) is successfully used in the disc identification area from the lead-in area It is written four times in four consecutive blocks counted from the beginning of the ', and all the first bytes in the disc identification information include a write protection flag.

When this flag value is 0b, it means the entire area of the disc It is rewritable. In other words, "quot" in Figure 9 is defined as follows: WP = lb: Except for the drive test area and the disc identification area, the entire area of the disc is write-protected. -〇b: The entire area of the disc is not write-prohibited.

But in the case of updating the write-protected information, only the updating action is performed. That is, because the information has not been read, a write time of a few hundred microseconds is hardly worth considering. Therefore, in consideration of the soundness of the information, a write operation in four locations is performed, and the ability to correct errors' is added to the calculation during recording. In other words, if both errors are not generated, or the normal correction flag is read, ^ when two items match each other, the write protection status of the disc is set to not read reserved The remaining flags therefore increase the speed of operation.
